arm a 9361 imm ma of mij wm View ...b C .nu cd Eiga 2o is had in position by am @new mf seat 23 and is connected by means of a ten= l sionirod 25 with'the control element 26 of `28 have outwardly extending the movement. Whenever the lever 2A is tilted about its base into any, angular position it draws'the tension rod 25 to the left. 'lhe lever 24 may be tilted into an desired angular position about its base an still effeet a movement of the tension member 25 to the left (Fig. 1), as readily apparent. 'Ifhel base late 20 has two side walls 27 and 28 exten ing upwardly therefrom, which side walls then have. inwardly convergin extensions 29. The sideA walls 27 an l lugs l30, which lugs carry fiber bearing sleeves 31. The movable switch arm 19 is rotatably seated upon the bearing sleeves 31 so that this switch arm 19' may be entirely insulated from the remaining parts of the operating mechanism.

The control element 26 is shown more clearly in Fig. 4 and this control element cooperates with an operating element 32. The operating element is loosely placed in the movement but confined in its position by having its lu 33 seated within the slots 34 provided in t e control element 26 and being united byfmeans of the spring 35 with the movable switch element 19. TheV spring is secured to the operating element 32 as shown l at 36 and the opposite extremity of the spring is mounted in the insulating lug 37,

this insulating lug 37 being mounted upon' the outermost extremity of the movable switch element 19, and projecting there'- lthrough as will be most clear from Figs. 1

and 2. Thus the movable switch element 19 is absolutely insulated from all of the remaining parts of the switch movement, including the elements 26, 32, 35, 20, 25, and 24. The left hand extremity (Fig. 1) lot' the operating element 32 is confined in its position by the plate extension 38.0n the one side' and by the extensions 29 on the other. The

operating element 32 has fingers 39, which fingers cooperate with the'right hand end faces (Fig. 1) of the extensions 29 and 38.

By r f'erring to Fig. 1, for instance, it is seen th t this operating element 32 is held in the lposition it occupies by having its lingers 33 held in the slots 34 and by having the spring draw its left hand extremity into engagement with the plate extension 33.

It' it is desired to reverse the position of the movable switch element 19, then the lever 24s is tilted about its base in any suitable manner, or if desired, bodilyv drawn to the left (Fig. 1), whereupon the tension element 25 is moved to the left, this drawing the con have ,the operating element 32 to swing about the,

right handed of the extension 29 in a clockwise direction, this movement contin-A until the left hand extremity o the um s ring 35 has passed beyond the center line of t eprojections 30. lDuring ali this movement the s ring 35 has n extended and immediate y the left hand extremity of the sp has passed above theprojection 3i), the movable switch elexnent 19 swings b snap action into the position shown in drawing the left hand extremity of the op erating element 32 toward the extension 29 by vsnap action. In this movement of the operating element 32, the lower iingers 39 assed interiorly .of the late extension 38 and have not engaged the right hand face of this plate extenslon. The minute the pull or tension upon the lever 2A isreduced, how* ever, so that the tension element 25 and the control element 26 may again move to the right the spring 35 draws these elements to the right, at the same time that it draws the operating element 32 to the right. As this operating element 32 is drawn to the right, the lower fingers 39 which are sliding along ig. 6, aiso A the upper face of the plate extension 38 l finally pass beyond the right hand extremity of this plate'extension and snap into position in a manner similar to that in which the element 32 is shown engaging the extensions 29 in Fig. 1. `The position now occupied by the parts is shown in Fig. 6. If then, the lever 24- isl again actuated to draw its tension member 25 to the left, the operating element 32 now swings contraclockwise about the right hand edge of the extension 38 as a pivot carrying the left hand extremity of the spring below the finger 30, whereupon the movable vswitch element 29 snaps into the position shown in full lines in Fig. 1.

It will thus been seen that the movable switch element 19 is entirely insulated from the remaining parts of the mechanism so that the lever 24ffor instance may be of metal if desired, without thereby creating any hazard'.

It will be understood, of course, that within the spirit of my invention the movable switch 'element 19 may be actuated by any pro nerly co-opcratedswitch movement.

I aving, however, thus described my Ainvention as being applied to a particular 'Form of movement, what l claim as new and desire to secure by Letters Patent is:

1. A switch movement having a pair of fixed contacts and a movable switch element adapted to bridge said fixed switch contacts to establish circuit connection therewith, a mount-ing .for said switch elementl having mit fixed pivot means for one end of said switch 1
